ABSTRACT:
A tool for reconditioning threads on vehicle lug studs. The tool is comprised of a hollow tube slidably receiving a collet chuck. The chuck is operatively connected to a handle that is in turn pivotably mounted to the tube. Pivotal movement of the handle causes responsive movement of the collet chuck between an extended and a retracted position within the tube. The chuck includes internal gripping surfaces having thread cutting serrations thereon. In the extended position, these serrations are separated from one another to enable loose positioning of the collet chuck over a lug stud. The handle is then pivoted to cause corresponding movement of the chuck to the retracted position. As the chuck is retracted into the tube, the gripping surfaces grip the shank between the thread cutting serrations. The tool may then be turned about the axis of the stud to renew or recondition the threads thereon.
